Question

The equation y=7.6x represents a proportional relationship what is the constant of proportionality?

A. 1/7.6

B. 7.6

C. x

D. y

Answer 1

Option B. 7.6

Explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
`y/x=k` or
`y=kx`

where

k is the constant of proportionality

The slope of the linear equation is the same that the constant of proportionality

In this problem we have

`y=7.6x`

so

the slope is
`m=7.6`

therefore

The constant of proportionality k is
`k=7.6`
